Answer:

x = 5, y = 1/2

Step-by-step explanation:

-3x - 4y = -17 Use the elimination method by adding the 2 equations together

5x+4y=27

2x = 10 ===> x = 5

3(5) + 4y = 17,

4y = 2 ===> y = 1/2

frozen [14]

Answer: 120

Step-by-step explanation:

Since the order of the numbers doesn't matter we can use the formula:

$\dfrac{n!}{r!(n-r)!}\quad \text{where n is the quantity of items and r is the quantity chosen}\\\\\text{In this problem, there are 10 numbers (n = 10) and 7 to be chosen (r = 7)}\\\\_{10}C_{7}=\dfrac{10!}{7!(10-7)!}\\\\.\qquad=\dfrac{10!}{7!3!}\\\\.\qquad=\dfrac{10\times 9\times 8\times 7!}{7!\times 3\times 2\times 1}\\\\.\qquad=10\times 3\times 4\\\\.\qquad=120$
